install openssl-devel on Mac

Question

I need to install the openssl-devel on Mac. But I've tried brew and macport both. Neither of them work.

And I have also googled this problem--- install openssl-devel on Mac. But, I did not find an exact answer.

Anyone met this kind of problem before?

Answer 1

brew install openssl@1.1

Don't copy anything, just set the PKG_CONFIG_PATH environment variable with the path to openssl's *.pc files:

export PKG_CONFIG_PATH=/usr/local/opt/openssl@1.1/lib/pkgconfig/

Answer 2

brew install openssl@1.1

cd /usr/local/lib/pkgconfig/

make symbolic links instead of copying

cp --symbolic-link /usr/local/opt/openssl@1.1/lib/pkgconfig/* .

Symlinks are now in the present working directory.

Answer 3

This has changed with the latest verison of brew on Big Sur (11.5.1) on a Macbook M1 (just for completeness):

export LDFLAGS="-L/opt/homebrew/opt/openssl@3/lib"
export CPPFLAGS="-I/opt/homebrew/opt/openssl@3/include"

Answer 4

I suppose you want to compile C++ program, and the C++ code include openssl headers, so just install openssl with brew:

brew install openssl

or install openssl 1.1.1 with

brew install openssl@1.1

Then you can find include and lib folder in /usr/local/opt/openssl@1.0/ or /usr/local/opt/openssl@1.1, and adjust your makefile, modify the path like this:

OPENSSL_DIR = /usr/local/opt/openssl@1.1
OPENSSL_SUPPORT = -I$(OPENSSL_DIR)/include -L$(OPENSSL_DIR)/lib

Answer 5

this command solve my problem:

brew install openssl@1.1
cp /usr/local/opt/openssl@1.1/lib/pkgconfig/*.pc /usr/local/lib/pkgconfig/
